I know I'd be insane to try it, but might anyone know how to locate the PLL resistors on a Titanium PowerBook G4 1GHz? I've disassembled the machine but have been unsuccessful in locating the appropriate area on the logic board.

i saw some shots for an older 500mhz g4 powerbook, but the design is different enough to need another look. everything is paired up. unfortunatly it looks like the right area, but without the whole layout, it can be difficult. i'm glad you are going all the way and overclocking your powerbook. very few people would do that, and that's dedication. looking foward to seeing the pic(s)

I don't know if this will help or not, but Sherlock has a language converter, useing C/P (Command C, Command V) you can take each paragraph out of the Japenese website, and convert it roughly to english. It should give the help you need....

First, the good news: the PLL clock table is correct. sysctl hw.frequency will give me the correct number after a power manager reset. Currently at 1.13GHz.

Now the bad news: soldering the voltage control is very touchy. I'm currently getting inconsistent readings from 1.22v to 1.52v. This may have something to do with the L2 cache being permanently disabled. The machine is now in "low power" mode for some reason. What does this mean for our hero? Well, it means his 1GHz Titanium with 1MB of L2 cache is now stuck at 667MHz with no L2 cache. Not exactly what I had in mind. Hopefully, this is a simple case of me screwing something up with the voltage soldering and not an issue with the mod instructions. I've tried various iterations of both the clock and the voltage control but nothing seems to bring back the L2.

Be warned! This is a very difficult mod and should not be taken lightly!
